The JFADW-05K power vehicle is a trailer-mounted AC/DC power supply unit. It utilizes a diesel engine as the primary power source to drive a generator, producing medium-frequency power. Through an external commutator, DC power is generated. The entire generating set and electrical control system are mounted on a trailer chassis. This vehicle can independently output both AC and DC power. Its working principle is based on power electronics technology, typically employing two core components: inverters and rectifiers. The main function of the inverter is to produce adjustable AC power from a DC source, while the rectifier converts AC power back into DC power.

When providing support for aircraft using 28.5V power, in 28V mode, it can output DC 28.5V for power-on and startup procedures. For aircraft requiring 115/200V 400Hz power, in 115V mode, it can output AC 115/200V for power-on and startup, and can also supply AC 36V for in-situ testing. When supporting aircraft that use both 115/200V 400Hz and 28.5V power, in 28V mode, it can output AC 115/200V and DC 28.5V simultaneously for power-on. While one aircraft is starting with DC 28.5V, another can continue receiving 115/200V power until the startup process is complete.

This product has extremely low environmental requirements and can operate normally even at altitudes of 3000 meters and under low-temperature conditions. Both the diesel engine and generator are nationally certified products, with emissions meeting environmental protection standards. Operating this vehicle does not require special safety measures, ensuring operator safety.
